FIELD: mechanical engineering. SUBSTANCE: spindle head has a housing and a spindle device having a spindle, a shell case, a mechanism for the tool clamping, a hydraulic cylinder for the tool squeezing out and a motor. The new feature of the device is that the electric motor is located coaxially with the hydraulic cylinder for the tool forcing out and is connected with the spindle directly through the intermediate shaft mounted for displacement relative to the shaft upper end being simultaneously the pusher of the mechanism for the tool forcing out.
